The 100 members of SNAP, HYDRO, and NYHOPS models take less than 3 h to complete using 1,000 computational cores.
The water level from the 100 NYHOPS ensemble members are used to compute the 5th, 50th, and 95th percentiles using a phase-aware statistics method (Schulte and Georgas 2018) in the HIHR boundaries.
HIHR retrospective forecasts were run using the NYHOPS forecasts issued at 0000 UTC 27, 28, 29, and 30 October 2012.
